Biography
Art Sneperger was born in Cleveland, Ohio to a working-class family, and he worked alongside his childhood friends Billy McComber and Danny Greene as a longshoreman. He became one of the original members of Greene's "Celtic Club" gang, and he built some of the bombs used to kill Greene's enemies. Sneperger would secretly become a police informant, however, and he revealed to the police that Greene was a top-echelon FBI informant. On 31 October 1971, Sneperger was sent by Greene to bomb Mike Frato's car, and Greene deliberately detonated the bomb as Sneperger was planting it, destroying the car and killing his former friend.
